TRACTION-ENGINE.

' Specification of Letters Patent.-

Application filed April 22, .1912.

Patented Jan. 21,1913.

Serial No. 692,449.

To all whom it may concern:

-Be it known that I, MoRoY DE Vinsn, a

'citizen of the United States, residing at Fresno, in the countyof Fresno and State of California, have invented a new and useful Traction-Engine, of which the, following is a specification.

This invention relates to plows and is more particularly an improvement upon the structure disclosed in an application filed by me on September 14, 1911, said application bearing'Serial N 0. 649,301.

One of the objectsof the invention is to provide improved means whereby motive power may be transmitted to all of the supporting wheels of the structure, thereby increasing the tractive force of the machine.

A further object is to provide improved means for transmitting motion from a single motor to the traction wheels and to the rotary plows used in connection with the machine.

A further object is to provide improved means for steering the machine-during the transmission of power to the steering wheels.

WVit-h the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a plan view of a plow having the present improvements combined therewith. Fig. 2 is a longitudinal section through the machine. Fig. 3 is a view partly in front elevation and partly in section of a portion of the machine.

Referring to the figures by .characters of reference 1 designates the frame of the ma' chine having a supplemental frame 2 mounted in the rear portion thereof and adapted to swing about a transverse shaft 3 as an axis, said supplemental frame carrying a central shaft section 4 connected, by

universal joints 5, to side shaft sections 6, all of said sections carrying rotary plows 7 of any preferred type. A bell crank lever 8 or the like is mounted on the rear portion of the main frame 1 and is connected, as

by means of a link 9 to the supplemental frame 2, there being any suitable mechanism,

such as a rod 10 and a lever 11 for actuating the bell crank lever 8 so as to shift the supplemental frame 2 and thereby raise or lower the rotary plows as desired. The shaft sections 6 can be swung relative to the central section 4 so as to bring the rotary plows on said section in any desired positions relative to each other. The mechanism employed for adjusting these sections can be of any desired construction and inasmuch as it constitutes no part of the present invention it is not deemed necessary to enterinto a detailed explanation thereof.

Shaft 3 is preferably formed in two sections connected by a difierential indicated generally at 12 said differential including an. external gear 13 receiving motion through a gear 14: from a longitudinally extending shaft 15 which is journaled on the main frame 1 and is connected, as by means of a universal joint 16, to a shaft 17 which, in turn, receives motion through a chain 18 and sprockets 19 and 20, from a motor 21 mounted on a platform 22 arranged preferably on the front portion of the frame 1. A stationary arched axle 23 extends transversely of the rear portion of frame 1 and has traction wheels 24 mounted for rotation I from,- through a chain 29, to a sprocket 30 secured to the middle section 1 of the shaft of therotary plow. .Thus it will be seen that when shaft 3 is rotated motion will be transmitted therefrom to the rotary plows and also to the two wheels 24 and, by providing the differential 12, said .wheels 24 are permitted to rotate at different speeds as when the machine is turning.

The front or steering axle 31 contains a shaft 31 which is adapted to rotate and is made up of two sections connected by a differential indicated generally at 32. The

front traction wheels 33 rotate with the sections of shaft 31 and said shaft sections are mounted Within and are adapted to shift with a yoke 34;- having a cup-like extension 35 at the top thereof. A shaft section 36 is journaled within the yoke itiprojects the extension 35 and has a stem 40 project ing upwardly therefrom and fixedly connected to frame 1. A shaft section 41 is journaled within the stem 40 and is connected to the per end of the shaft section 36 by a universalvjoint 42. 'The upsect-ion 41 has a gear 413 meshing with anothergear 1% which is secured to a shaft 45. This shaft is adapted to receive motion from the shaft 17 through a chain 16 and-sprockets 47 and 48.

From the foregoing it will be seen that motion can be transmitted from the motor 21 to the front shaft 31 irrespective of .the angle to which the main frame 1 maybe shifted relative to the front axle 31 and also irrespective of the horizontal angular adjustment of the front axle. ,Eor the purpose of reinforcing the connection between the front axle and the main frame, an extension 49 extends forwardly from the yoke 3e and its front end is adapted to travel within an arcuate guide-5O connected to the front end portion of the main frame 1. Another extension 51 extends rearwardly from theaxle and is adapted to travel within an arcuate g' ide52 connected to the mainframe 1. The steering chains or cables 53 are connected to this extension 51 and extend laterally. into engagement with guide sheaves 54 at the sides of the main frame 1. Said chains or cables then extend inwardly to suitable actuating mech- Copies of this patent ma he obtained for the front portion of the main five cents each, by addressing th Washington, D. 0.

anism designated generally at 55 and which is adapted to be operated by means of a steering wheel 56 of the usual or any preferred construction.

As shown in Fig. 3 springs 57 connect the end portions of the axle 31 with a frame 58 on which are disposed bearing members 59 adapted to. be contacted by blocks 60 extending downwardly from the front portion of the frame 1, thus to prevent the front end of the frame from tilting to an undesirable extent relative to the axle.

hat is claimed is A machine of the class described including a front axle, said axle having a yoke, shaft sections journaled within'the axle, a differential connecting the sections, an extension upon the yoke, an upstanding shaft section journaled in the extension and yoke,

means for transmitting motion therefrom to the differential, a main frame, a bearing member fixedly connected thereto and'bear a shaft withinsaid V ing within the "extension, bearing and connected by a universal Joint to the upwardly extending shaft section in the extension, springs upon the end portions of the axle, a

and means upon the sides of the main frame for contacting with said bearing members to limit the tilting movement of the main frame relative to theaxle.

In testimony t-hatlclaim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
